MC33063A

illustrate

The easy-to-use chips of the MC33063A and MC34063A contain all the major circuitry needed for building simple DC-DC converters. These devices primarily include an internal temperature-compensated reference, comparator, an oscillator, an active current limit, a drive PWM controller, and a high current output switch. Therefore, the device requires minimal external components for the construction of boost, buck converters and inverter topologies.

The MC33063A features operation from -40°C to 85°C, while the MC34063A features from 0°C to 70°C
